Agreed. This happened to me. I had to go into the BIOS and switch from CSM/Legacy to UEFI mode first, and then the Secure Boot option became available. Hope that helps.

Same here. Yeah, that's exactly it. Also, make sure you save and exit after switching to UEFI, then go back in to find Secure Boot ready to enable.

Yeah, Agreed. Also, double-check that your drive is using GPT and not MBR, as that can lock the option too.

This, and sometimes you also need to clear any existing platform keys in the BIOS to reset it.

Can confirm. I had the same problem. For me, I also had to disable CSM support in the BIOS completely before the Secure Boot option even became available to turn on.

Same here. You could also check if you need to switch the BIOS from "Custom" to "Standard" Secure Boot mode, which sometimes unlocks it.

+1 Also, have you cleared the TPM or reset your BIOS to factory defaults since the upgrade?

Yeah, Did you also switch your BIOS from Legacy/CSM mode to UEFI-only?

+1 Agreed, switching to UEFI is usually the fix. Also, you might need to set a supervisor or administrator password in the BIOS first—some systems lock that setting behind it.

+1 Yeah, and after you set that password, don't forget to clear any existing TPM/security keys in the BIOS before you try turning Secure Boot on.
